Dawes Devices Diesel MK II Hybrid Boost Controller


  • The fastest reacting boost controller on the market!
  • Quick Boost Rise for more area under the boost curve and wild mid-range torque!
  • Updated version of the Original Dawes Device Manual Boost Controller. This is not your Dad's g-valve!
  • We pioneered the use of synthetic materials in an MBC and have improved !

We've been making the fastest boost controller for over 13 years. Now we've updated it with a smaller, lighter valve body and new synthetics. Precision ground ball seat with custom angles that aren't even available on lesser boost controllers. 100% US made (no cheap Asian copies here), individually tested for 2 weeks, guaranteed for life! Install this boost controller and forget about it, because there is nothing better anywhere, at any price!
